UNITED STATES CARL GEBHARD, OF LONG BEACH, CALIFORNIA.

SLIDING CASTER.

Application filed September 15, 1922. Serial No. 588,454.

To all whom it may concern:

Be it known that I, CARL. GEBHARD, a citizen of. Germany, and a residentof Long Beach, in the county of Los Angeles and State of California,have invented a new and Improved Sliding Caster, of which the followingis a full, clear, and exact description.

' The present invention relates to new and useful improvements in chairattachments and it pertains more particularly to a pad or foot therefor.

It is the primary object of the invention to so construct the chair padthat a rubber or other suitable cushioning element is combined with ametal cap to prevent wear of the cushioning element, and, at the sametime, facilitate moving of the chair.

In devices of this character it is quite common to employ metallic capswith cushioning elements of rubber or the like, but in the most commonforms of this combination,

owing to the weight to which the chair is, subjected, the metallic capcuts through the cushion and destroys the resiliency thereof since anycompression of the cushioning member is occasioned in such devices bythe defining edge of the metal cap.

It is one of th primary objects of the present invention to'so constructthe cushioning element and the metal cap that the maximum amount of.resiliency is had thus greatly increasing the cushioning effect of thecushioning element.

It is a further object of the invention to provide a new and improvedmeans for attaching the metallic cap to thecushioning element to preventaccidental displacement of one relative to the other.

It is a further object of the invention to so construct the metallic capthat the same will have no injurious effect upon the cushioning element.

It is a still further object of the invention to so construct themetallic cap that a maximum amount of resiliency and cushioning effectof the cushioning element will be had.

With the above and other objects in view,

reference is had to the accompanying draws ings, in which Figure 1 is adetail view of a chair leg showing the cushioning element of theimproved chair pad in position thereon;

Fig. 2 is a bottom plan view of the cushioningelement;

Fig. 3 is a detail view of a chair leg, partly is secured to the chairleg 11 by means of a. 7

suitable fastening 13, which is shown in the form of a driven-headfastening but it is understood that the same may be of thescrew-threaded type if desired. The cushioning element 12 is providedwith a reduced extension 14 and said reduced extension provides anannular shoulder 15 at the base thereof. The opposite end of the reducedex tension 14, which forms the outer extremity of the cushioning element12, is further re-' duced as at 16, and said reduction 16 forms ashoulder or the like, 17. This cushioning element 12 is provided on itsouter end with a countersink or recess 18 in which the head 19 of thefastening element 13 is adapted to be received. In order to moresecurely retain the cushioning element 12 in position,

a washer 20 is provided through which the fastening element 13 passes,it being understood that the' washer 20 is of a size or diameter whichretains it within the countersink or recess 18 of the cushioningelement.

The reference character 21 designates a metallic ring and said metallicring is adapted to surround the reduced portion 16 of the cushioningelement and be received on the shoulder 17 formed thereby. As moreclearly shown in Fig. 2, this metallic ring 21 is split as indicated bythe reference character 22, in order that the same may be reduced indiameter for the purpose to be hereinafter described. The referencecharacter 24: designates the metallic cap member, and said cap member isformed with angular side walls 25, which terminate in an annular flange26 angularly disposed with respect to the side walls 25. Thls annularflange 26 is adapted to engage the shoulder 15 of the cushioning element12, as is clearlyshown in Fig. 3, and the metallic member 24 serves asthe foot or tread element of the pad.

In assembling the device, the cushioning element is first positioned on.the end. of th'e'leg 11 and is secured thereto by the fastening 13.After this has been done, the

side walls 25 of said metallic cap member "24, the same is maintained inposition. In

lacing in position the metallic member, the iiretallic ring 21 will becontracted to permit of'the' metallic member passing over the reducedportion of-the cushioning element 12. Immediately the metallic member 24is positioned, however, the metallic ring 21 expands to retain themetallic member 24: in position with respect to the cushioning member 12and the leg 11. By this con struction it is apparent that the flange 26of the metallic member 24 engages the cushioning element and that thecushioning element is protected by this broad flat surface to a greaterextent than would be the case were the flange 26 omitted and an edgepresented to the cushioning element which would serve to cut through thesame as is vthe common practice.

What is claimed is: I 1. A pad for chairs comprising a cushioningelement, a metallic foot member adapted to receive the cushioningelement, and a flange formed on said metallic foot member and adaptedfor engagement with the cushioning member, substantially as described.

2. A furniture pad comprising a cushioning member, a metallic memberadapted to receive the cushioning member, and resilient means carried bythe cushioning member for maintaining the metallic member-1n posltionthereon.

3. A pad for furniture comprising a member in the form ofa shell adaptedto receive the reduced extension of the cushion element, and an annularflange formed on said metallic foot member and adapted to engage theshoulder at the base of the reduced portion of the'cushion element.

5. In a pad for furniture, a resilient member having a reducedprojecting portion forming an annular base flange, and a metallic shellmember adapted to receive said reduced projecting portion, said metallicadapted to engage the base flange of the resilient member and compressthe same when pressure is applied to the chair. 1
